LOCOIVIOTIVE ASH-PAN.

SPECIFICATION forming part of Letters Patent No. 302,915, dated .August 5, 1884.

l l Application tiled April 12, 1884. (No model.)

T0 all whom it may concern.'

Be it known that I, CHARLES M. LAKE, a citizen of the United States, residing at Jackson, county of Jackson, State of Michigan, have invented a new and useful Improvement in Locomotive Ash-Pans, of which the following is a specification.

My invention consists in an improved apparatus to utilize the exhaust steam from the cylinder, in preventing the contents of the ash-pan from freezing, and in clearing the ashpan of said contents. Other. incidental ohjects "will appear in the description and claims.

In the drawings forming a part of this speciiication, Figure 1 is a side elevation of a locomotive-boiler with apparatds attached, parts being broken away; Fig. 2, a top View ofthe ash-pan, parts being broken away; Fig. 3, aseotion of Fig. 2 on line 2 2 and a vertical broken section ofthe boi1er-arch,with which the ashpan is connected; Fig. 4, a broken detail of Figs. 1 and 27 in section, enlarged; Fig. 5, a perspective view of the skeleton-frame of the ash-pan; Fig. 6, a perspective of condenserbottom to ash-pan, with parts broken away; Fig. 7, end view of Fig. 8; Fig. 8, side elevation of a cylinder enlarged, with connected parts broken away; Fig. 9, a top view of a portion in Figs. 1 and 8, enlarged; and Fig. 10 is an end view of the upper portion of the boiler in Fig. 1; Fig. 11, a check-valve, and Fig. 12 a section of pipe, showing its location and use.

The boiler is illustrated in Fig. 1 at E, portions being in dotted lines.

D is one of the cylinders, the other being on the opposite side, in the usual manner of locomotive-engines. The exhaust-ports e e of the cylinder D, on the under side thereof, are provided with pipes in which the stopcocks r r are located. These stop-cock pipes extend laterally toward the trucks, (not here shown,) Figs. 7 and 9, and are connected by a pipe, a. The three-way stop-cocks or valves 1' r are connected by an operating-rod, t. The use of these cocks' is explained in the description of the operation. In the ports e e may be located valves g, which will admit the passage of steam out of the ports and prevent its return, as shown in Figs. 11 and 12. A pipe, S, connects the pipe a with a steam-condenser, A, beneath the arch or fire-place R of the boiler E. A heater-pi pe, a, connects the pipe a of one cylinder with said pipe of the other cylinder on the opposite side, (not here shown,) by passing over the boiler E, Figs. 1 and l0.

The skeleton ash-pan frame B is provided with a detachable bottom, A, said bottoni being the condenser heretofore mentioned, Figs. 5 and 6. This condenser consists of a frame and an upper and lower inclosure, C P, bolted to said frame. In Fig. 6 the upper inclosurc, C, is broken away, showing central supports, c c. These supports are provided with notches c e, to admit the passage of steam and water all through the condenser. The steam-pipe S passes through the side wall of the skeletonframe B and enters the condenser, one on each side from each cylinder, as 'shown in Fig. 2. Pipes c c are connected with the pipe S, and extend laterally therefrom over the front end of the condenser A. VThese pipes a a" are provided with ports c', for admitting steam into the ash-pan and blowing the contents therefrom. This is done by turning the threeway cocks u, Fig. 4, in a manner to shut the steam from entering the condenser and admitting it into the pipes c, as in said iigure. Draft-pipes o o are connected with the corners of the condenser and extend to the rear of the boiler-fines, and enter below the smoke-stack in the usual manner. The condenser is provided with a discharge-pipe, b, which is extended upward, terminating at a proper height to govern the desired amount of water in the condenser.

The pipe d is designed to connect with the exhaust-pipes of a steam-propelled engine which operates the brakes, in order to convey the exhaust-steam from said engine into the condenser. Thus all the exhaust-steam from the entire locomotive construction is conveyed to the same condenser. This engine and exhaust-pipes which are to connect with pipe d are not here shown, said pipe ci being extended upward and broken away.

Then the three-way cocks r r are set, as in Fig. 9, the exhaust-steam from each end of the cylinder D is conveyed to the condenser A, where it is converted into water which keeps hot and prevents the contents of the ash-pan resting on the plate C from freezing in cold weather. It prevents visible exhauststeam, and the steam may be used to free the IOO ash-pan of its contents, which two llatter-named functions are useful, even in warm weather. By turning the stop-cocks in the proper position the exhaust-steam may be blown out of ports 3 2, Fig. 9.

Near the front of the boiler, .on top, is an indicator, F, connected with the boiler E by heater-pipe H. With this pipe and indicator are connected the branch heater-pipes n, hereinbefore referred to. rIhe pipes H and n are provided with stop-cocks, as in Figs. 10 and 4l. By this means steam may be circulated from the boiler through the pipes n, H, and S,

into the condenser when the exhaust-ports of the cylinders are closed by the stop-cocks r r, to prevent danger of freezing up. By means of the indicator the engineer can tell from the oscillation of the hand that the exhaust-ports e e are open, as a greater circulation of steam passes through the pipes n n when said stopcocks r r are turned to open the ports e e.

Having thus described my invention, what I claim as new is- 1. The combination, with a cylinder and a pipe connecting the ports, provided with the three-way cocks and check-valves, of a condenser located beneath the ash-pan, and a connecting-pipe' adapted to convey the exhauststeam to said condenser7 substantially as set forth.

2. The combination, with a cylinder having the connecting-pipe between the ports and provided with the three-way stop-cocks, of

'of said pipe and lateral branches three-way cocks, whereby steam may be let into the branches or the condenser, substantially as set forth.

4. The combination, with the cylinders, an indicator, a pipe connecting said indicator with the boiler, and heater-pipes connecting the indicator with the exhaustports of the cylinders, of an ash-pan and condenser and pipes connecting the exhaust-ports with said condenser, said exhaust-ports provided with suitable stop-cocks and clieckvalves, all substantially as set forth.

In testimony of the foregoing I have hereunto subscribed my name in the presence of two witnesses.

CHARLES M. LAKE.
